6.3  

Calculation of the fans' air flow 

 

You can obtain the air flow that moves each of the dehumidifier's fans by using the following 
equations: 

 

 

 

 

Q 

 = Air flow in m3/h. 

rho 

= Density of the air as it passes through the fan in kg/m3.

  

BQ1 

= Differential pressure measured by the process fan probe in Pa. 

BQ2 

= Differential pressure measured by the reactivation fan probe in Pa. 

 

(See point 8.10 of this manual to find out how to obtain the values BQ1 and BQ2 from the 

unit's display).
